How can i fix my cash register Sharp XE-A203?

You have accidentally re-programmed the CASH (TL) button while trying to program something else.
Try this:


Turn key to PGM mode
008
X (next to decimal point)
#/TM/ST (SUBTOTAL button)
TL/NS (CASH button)

Note: on some versions, #/TM/ST is called SUBTOTAL and TL/NS is called CASH
